Description

  • The present invention relates to a coupling assembly for connecting a towed implement to a prime mover.
  • Tractors and utility vehicles used for agricultural work may be coupled to towed implements which have hydraulic couplers which must be connected to complementary hydraulic couplers of the tractor or utility vehicle. Implements are not utilized full time with the tractor, so it is desirable that a coupling assembly allows quick, easy removal and reinstallation of the implement. Flat face hydraulic quick couplers need to be mechanically locked together because of the hydraulic separating forces. Others have used an external locking lever which must be operated manually. An improved coupling assembly is needed for an implement that can be quickly and easily connected and disconnected from a tractor. Furthermore, a mechanically lock coupling is needed that can reduce the difficulty of securing hydraulic couplers of the tractor to hydraulic couplers on the implement.
  • These and other objects are achieved by the present invention, wherein a coupling assembly for coupling a towed implement to a prime mover is provided. The coupling assembly comprises a manifold which can be mounted to the prime mover, and a coupler frame which can be mounted to the implement. A pivot pin projects laterally from a side of the manifold . A lever member is pivotally mounted on the pivot pin . The lever member has a hub which rotatably receives the pivot pin, a first arm projecting away from the hub, a second arm projecting away from the hub, a latch pin projecting laterally away from the first arm, and a locking recess formed by the second arm. A lock pin projects laterally and is supported by the coupler frame. A latch member is fixed to the coupler frame . The latch member has a body, a latch finger spaced apart from the body, and a spacer connecting the latch finger to the body. The body, the latch finger and the spacer form a slot therebetween. The body forms a slot wall which is spaced apart from the latch finger and which faces the latch finger. The body also forms a latch wall which is joined to the slot wall. The latch wall engages the latch pin, pivots the lever member and moves the latch pin into the slot as the coupler frame moves towards the manifold. The second arm moves to a locking position wherein the locking recess receives the lock pin as the lever member is pivoted by the latch member.

    is a perspective view of the coupling assembly of Fig. 1 mounted on a pickup hitch.
  • Referring to Figs. 1 to 3, a coupling assembly 10 is provided for coupling a prime mover, such as a tractor, to an implement towed by the prime mover. A housing member or manifold 12 is mounted to a structure 14 of the tractor. A implement member or coupler frame 16 is mounted to the implement. An implement plate or couple plate 18 is movably supported by the coupler frame 16. One or more hydraulic and/or electric implement couplers 20 are installed in the coupler plate 18. As best seen in Figs. 2 and 4, support brackets 22 project inwardly from the coupler frame 16. Each support bracket 22 has a bore 24 which receives a support bolt 26. Each support bolt 26 has a threaded end 28 which is threadably received by a corresponding threaded bore 30 in the coupler plate 18. A resilient spring member 32 is mounted around each support bolt 26, and is biased to urge the coupler plate 18 towards the manifold 12. Alignment dowels 34 project from the coupler plate 18 towards the manifold 12 and are received by alignment bores 36 formed in the manifold 12. The manifold 12 supports hydraulic and/or electric tractor couplers 40 which are matingly engagable with the implement couplers 20. The coupler frame 16 may be pulled towards the manifold 12 by a conventional pick up hitch (Fig. 7).
  • As best seen in Fig. 1, a pivot pin 42 projects laterally from a side of the manifold 12. A lever member 44 is pivotally mounted on the pivot pin 42. The lever member 42 has a hub 46 which rotatably receives the pivot pin 42, a first arm 48 projecting away from the hub 46, and a second arm 50 projecting away from the hub 46. The lever member 44 also has a latch pin 52 which projects laterally away from an outer end of the first arm 48. The second arm 50 includes a first leg 54 which is joined to the hub 46 and a second leg 56 which extends away from the first leg 54. The first and second legs 54 and 56 are angled with respect to each other to form a locking recess 58.
  • Also as best seen in Fig. 1, a latch member 60 is fixed, such as by bolts, to the coupler frame 16. The latch member 60 has a body 62, a latch finger 64 spaced apart from the body 62, and a spacer 66 which connects the latch finger 64 to the body 62. The body 62, the latch finger 64 and the spacer 66 form a slot 68 therebetween. The body 62 forms a slot wall 70 which is spaced apart from the finger 64 and which faces the finger 64. The body 62 also forms a latch wall 72 which is joined to the slot wall 70. A lock pin 71 projecting laterally from the coupler plate 18.
  • As best seen in Figs. 1 and 2, a stop member 74 is formed by a hydraulic fitting which is attached to the manifold 12 spaced apart from the pivot pin 42. The lever member 44 has an uncoupled position wherein gravity moves the first arm 48 towards the latch member 60 and moves the second arm 50 into engagement with the stop member 74.
  • As best seen in Figs. 3 and 4, a pair of alignment dowels 34 projects from the coupler plate 18. The manifold 12 includes a pair of alignment bores 36 which receive the alignment dowels 34.
  • As best seen in Figs. 5 and 6, the latch wall 72 engages the latch pin 52 and pivots the lever member 44 and moves the latch pin 52 into the slot 68 as the coupler frame 16 moves towards the manifold 12. Also, the second arm 50 moves to a locking position wherein the locking recess 58 receives the lock pin 71 as the lever member 44 is pivoted by the latch member 60.
  • Referring to Fig. 7, a tractor pick up hitch 80 is mounted at the rear of a tractor frame part 82. The pickup hitch 80 supports the coupling assembly 10 which includes the structure 14 and the coupler frame 16.
  • The result is a coupling assembly 10 which can automatically connect and lock flat face hydraulic quick couplers together using a conventional pickup hitch 80 without leaving the tractor cab. The hydraulic cylinder of the pickup hitch 80 brings the hydraulic flat face quick couplers together so that the coupling assembly 10 automatically mechanically locks the tractor couplers 40 and the implement couplers 20 together. A couple plate 18 supports the implement couplers 20 facing a manifold 12 which is attached to a structure 14 of the pickup hitch 80. Resilient spring members 32 movably hold the couple plate 18 to a coupler frame 16 which is fixed to the implement. As the hydraulic cylinder of the pickup hitch 80 pulls the coupler frame 16 to the tractor, the couple plate 18 contacts the manifold 12. The hydraulic cylinder continues to pull the coupler frame 16 towards the tractor, compressing the resilient spring members 32 and preventing damage to the couplers 20 and 40. The additional coupler frame movement actuates the latching and locking mechanism. The resilient spring members 32 also allow for some coupler frame movement without the coupler frame 16 losing contact so the mechanical lock can be released prior to pulling the couplers 20 and 40 apart.
